  avr32 : remove explicit support
  The vendor has long since switched to Arm, with the last product
  
  reaching their official end-of-life over 11 years ago. Linux support for
  
  the ISA was dropped 7 years ago. More importantly, this architecture was
  
  never supported by upstream GCC, and the vendor fork is stuck at version
  
  4.2, which FFmpeg no longer supports (as per C11 requirement).
  Presumably, this is still the case given the lack of vendor support.
  
  Indeed all of the code being removed here consisted of inline assembler
  
  scalar optimisations. A sane C compiler should be able to perform those
  
  automatically nowadays (with the sole exception of fast CLZ detection),
  
  but this is moot as this architecture is evidently dead.

• How to run FFMPEG with —enable-libfontconfig on Amazon Lambda

  20 avril 2024, par Adrien Kaczmarek

  Problem

  


  I want to run FFmpeg on AWS Lambda (Amazon Linux 2) with the configuration --enable-libfontconfig enable.

  


  Situation

  


  I already have FFmpeg running on AWS Lambda without the configuration --enable-libfontconfig.

  


  Here is the step I took to run FFmpeg on AWS Lambda (see official guide) :

  


  

  • Connect to Amazon EC2 running on AL2 (environment used by Lambda for Python 3.11)

  


  • Download and package FFmpeg from John Van Sickle

  


  • Create a Lambda Layer with FFmpeg

  


  


  Unfortunately, the version built by John Van Sickle doesn't have the configuration --enable-libfontconfig enabled.

  


  Unsuccessful Trials

  


  I tried to rebuilt it from scratch following the installation guide but without success (and the guide doesn't install font related dependencies)

  


  I tried to install it with brew but the command brew install ffmpeg didn't succeed on AL2.

  


  I tried to install ffmpeg from ffmpeg-master-latest-linux64-gpl.tar.xz. Unfortunately, this build of ffmpeg doesn't run on AL2 :
